Episode notes

Stephen weinberg's model of leptons suddenly became hugely important. He used the idea of spontaneous symmetry breaking to explain what they thought would be the strong interactions. It was an idea, was a model. Was on the market there. But one of the reasons why it was ignored was because at the time, in the 19 sixties, the state of quantum field theory was that people were concerned about renormaliz ability.

Welcome to the November 2021 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
